What does the "three-click rule" suggest for web navigation?

The "three-click rule" suggests that users should be able to find any piece of content within three clicks from the homepage, which is crucial for optimizing accessibility and enhancing user experience. This rule emphasizes the importance of intuitive navigation, as it helps users quickly locate the information they need without becoming frustrated or lost. By ensuring that important content is easily accessible within a few clicks, websites can provide a more efficient and user-friendly experience.

This approach also aligns with the principles of usability and accessibility, as it recognizes the varying levels of digital literacy among users. Making content discoverable within three clicks supports users with cognitive or mobility impairments who may struggle with complex navigation structures.

The other options do not relate to the primary intention of the three-click rule: B focuses on the purchasing process, which is not directly connected to general website navigation. C incorrectly implies a limitation on the number of options shown on each page, which is unrelated to the concept of click depth for finding content. D suggests a constraint on clicks before needing a page refresh, which is irrelevant to user navigation pathways on a website.
